MATLAB: How to check if a value is a correct color

checkingcolorisvalid

Whether there is a function like

logical = isvalidcolor(value)

to check if some value may be used like a color (one of values specified in ColorSpec e.g.)

Not that I'm aware of - there's just not that much need - though you could write one if you want.

Do not do

if color=='black'

do this instead:

if strcmpi(color, 'black')

You can use the few matlab built in colors ('red','green,'blue,'black','white','cyan','magenta','yellow'),

plot(...,'color','green',...)

but you could also just declare a variable that is that vector, i.e.

g = [0 0 1]
plot(...,'color',g,...)
